CONTROLLING MEANS FOR MULTIPLE FUEL BURNERS. f

Application filed November 26, 1923. Serial No. 677,146.

The present invention relates to valve con-l trolling devices for regulating the fuel sup-` ply to burners, and has for its principal. object they provision of' a novel controlling mechanism for regulating the supply of two or more .different kinds of fuel to burners,

fuel tothe burner, independently of anyv other manual or remote-control means which may bel provided for the ordinary regulation of the burners operation.

For ,embodying the proposed improvements, l provide a valve structure through which'a pair of separate fuel passages ar formed for supplying two different vkinds of fuel to the burner, together with separate and independent valves for controlling the How of fuel through said' passages, and-suitable means for controllingl the positions of these valves in response to either a manual controlling device or automatic or remotecontrol devices, and also an automatic safety cut-off device operating independently of any of the other-controlling means. In the form of construction herein illustrated, the valves are arranged in connection with 'suitable diaphragms in a valve casing having the necessary independent fuel passages, which di'- aphragrns are Controlled to maintain the 'valves normally closed, but adapted to be actuated in response to the action of the 'controlling mechanism for opening the valves to the proper extent and in the desired vsequence, according to the requirements of the burners operation. v

It is further desired to devise a valve structure especially adaptedV for controlling the supply of both oil and gas to the burner, and having means for controllingthe operation of the oil and gas valves for opening the gas valve prior to the opening of theioil valve, and thereafter permitting automatic closing of the gas valve while maintaining the oil valve open for the purpose of feeding oil alone to the burner. In this connection, means is also provided for automatically closing an electric ignition. circuit bythe valve-opening Vmovement of the valve-controllingv mechanism, for the purpose of ig- 'ect of the invention CEN 1i nitingthe gas which` is admittedfto the l. burner by the opening ofthe gas lfeeding valve. Y V- It is further sought to'provide, `in connection: with t-he remote-control, connection 'for operating the duplex valve structure, a retarding device `operating to retard the valve-opening movement of the valve-regulatingmeans, in order thatl thev supply of fuel may' not be admitted to theburnerI s abruptly asto floodits operation. I

In the construction of vthe automatic safety cut-ofi:1 device, itis preferred also to include afusible connection adapted to permit operation of the cut-olf device in-they case of a lire in the. vicinity lof thevalve being hot enough to melt this vfusible connection, and thereby close the'burn'er valves through the vmedium of the same valve-closing connections as are Y operated by the!A weight of oiloverflowing from the burner, y

as above referredto.

lith they foregoing view, the invention willv now be described by reference to the accompanying drawings illustrating an e'liicient and practical form of embodiment of the; same, after which those lfeatures deemed to be. novel willl be particularly set forth in claims.

vReferring now to `the lraWings inv detail, these illustrate the improved valveconstrucf tion as comprising a sectional lvalve casing llt) FigureS is a detail elevationuofthe partsy `ample, gas, which may loe admitted from a made up of two outer'casing sections `l2, 13, of substantially semispherical form, and an intermediate substantially cylindrical section 14 clampedfbetween sections l2and 18,:and maintaining a pair of flexible or resilient diaphragm partitions "15, 116, inv adjacent parallel relation, as illustrated in `Figure 3. By this.

means, separate fuel passagesare provided in the .valve casing structure, for accommodating` .different Akinds o'f fuel, as for engas supply pipe 17 into the fuel passage .18 insidethe casing section '12, whereas oil, for

' example, admitted from an oil supply pipel "19, maybe received in' the fuel passage 2()y inside the casing section 13, from which sections feed pipes 2l and 22 may be'suitably arranged'forlfeedingthe gas and oil, respeci tively,to`the hurner (not shown).

' valve lports 23 The fuel is designedvto'be admitted into the passages 18 and 20through interior' valve ports 23 and 24, respectively, vwhich are conl trolled by. valves 25 rand 26, respectively, carried bythe diaphragms 15 and 16. respectively, .the arrangement vbeing such vthat the diaphragmstend. to maintain thevalves normally in open position, which actionof the diaphragm is"reinforced by means of coil springs 27 suitably ,arranged around the valves and between the diaphragms and i and 24, as clearlyillustrated in Figure '8.

The mechauism'foi' maintaining the valves yieldinfrly closed, andxpermitting the required i n opening movement-s of the same, will now be described; In 'thevalve casing section 14 is-mounted a. Vpair -of bearing sleeves 30 l (see Figure 4), for' accommodating the shaft portions 3l of a pair of crank` arms 32 formed on the inner 'ends of said shaft portions-and extending upright intermediate the centralportions of the'diaphragm 'ineinkbers l5 and 16 in aosition for engagement with knobs or' bosses33 secured to the valve stems on the inner faces of said diaphragm. The outer end of eachvof the shaft portions 3l hasiixedly secured thereto a vstop linger 34 (see Figures l and'4). On one ofthe bearing Sleeves fthe one at 'the left in Figure l) is ourna'led a pair of oppositelyacting rocherv arms 36, 3.7, each'provided with suitable stop screws 38 for adjustabe engage- Cil ment withxthe stop fingers 34,for `the rpurpose of limitingthe movement of the rocker armsin-response to the action of a coil springr 89 interposed between Vcorresponding ends of said rocker arms, as clearlyshown in Figriresv l and 7. The action" of this spring` is ofcourse to rock the cran'lrarins'32 in opposite outwarddirectionsadapted to maintain `the valves closed against the action ofthe springs '27, -which Vvalve-closing tendency of 'the spring S'Qfis adapted to be conveniently regulated `-by ysuitable adjustmentv of the screws 38, in an obvious manner.

The opposite ends of the roc-kei' arms 36 and', that is, the ends opposite the coil .i

spring 39, are provided with suitable rollers v42 kand 43, respectively, to be operatedvby the movements of an arm 44 journaled upon therighthand ysleeve 301m Figure 1,v and carrying a counter-weight 45 and also provided with a remote-control chain 46, which lattermay be operated either manually or automatically by the action of a `thermostatin a manner well-understood.. The'inner end ofthe arm L44 carries a lzeaff spring 4'?, the free end bf which is adapted for successive engagement with'the raised `vportions `of a segmental cam 48rjournaledupon Jthe same sleeve 3() as kthe arm 44, for rotating said cam into ,lifting-engagement withthe roller on the rocker arm 36, wherebyvthe tension oftthe spring 39 is relaxed as'regards its action on the stop''nger 34 corresponding to `the valve Thesegments of the' cam 48 are so divided asto result in the operative downward movement of the arm 44'not onlyv opening-the valve 25 rbut also permitting the same to beclosedbefoitethe downwardmovement of the arm 44 is completed,this result being accomplished by the roller 42 dropping into the next succeeding depressionen the cam member 48. The other roller 43, on the rocker arm 37, 'is/operated by engagement with a cam .bushing 49 secured "by a clamp screw 49 (Figure 4) tothe-hubpor.- tion` of theoperating arm 44, `and `ofvsuch a contour as lto allow the valve 26 to be entirely closed by the action of thespring 39 in the raised position ofthe arm 44, :but

tending tofinitiate:openingmovement of said valve after the gas lvalve 25 'has been par tially opened, andftliereafter'to increasingly open the oil valve 26 during the remainder of the lowering movement of the arm 44,this

result lbeing accomplished by relaxing the tension oftliespring 39 as applied tov the' and stopflinger y It is also preferred to provide the op'eraty ing lever 44 with a retarding device, de-

signed to retard the `downward or valveopeningmovement of the rsame, this de "ce comprising adash-pot cylinderf() prov` Jd with a plunger rod 'liwliich'isconnected a link 52 with the arm l44. The construction and operation of this retarding device is in all respects -substantially identical 'with 4that in 'my ce1-pending application Serial VNO@ 599,400, lled November 6, 1922. 1

,In order that thefmovements'of the oper` ating arm 44 may also control auton'iatically the ignition operation'otA the burner, l proy posetoprovide an ignition sparkingv device p 53fat'the burnefslocation, this spark plug being in an electric circuit 54 lincluding a suitable'battery 55 (see Figure 9),"vibrator 56 and condenser 57, (dosingcontacts, one ol:l Vwhich contact elements 58 is 'mounted and suitably insulated onv the cylinder l50, while 'the other contact element 59 is 'formed as a partvof .thef link 52 (see Figure 2).
